The Prysmian Afumex Green 1000 building cable - safer low-smoke wiring for modern infrastructure

Afumex Green 1000 cable from Prysmian sits coiled on a concrete floor, its bright white sheath streaked with dust from a long day of pulling through conduits. An electrical contractor rubs the jacket between his fingers and notes that it feels surprisingly smooth and flexible for a safety-focused cable, making long ceiling runs less of a fight.

Halogen-free focus and fire safety

Afumex Green 1000 is part of Prysmian’s Afumex portfolio of low-smoke, halogen-free cables designed to reduce toxic emissions in case of fire and improve visibility for evacuation teams. The series targets building wiring in residential, commercial and public infrastructure projects where safety codes increasingly favor low-smoke insulation.

According to Prysmian’s product materials, Afumex cables are engineered to meet stringent fire performance standards such as low smoke density and reduced corrosive gas release, which are critical in enclosed spaces like apartment blocks, schools and hospitals. In practice, that means less black smoke and fewer acidic fumes when a short circuit or external heat source causes cable insulation to burn.

Positioning in Prysmian’s building portfolio

Prysmian’s building segment spans standard PVC-insulated wires, enhanced fire-resistant cables and specialized low-smoke, zero-halogen offerings. The Afumex Green line sits toward the safer end of that spectrum and targets mid- to high-spec projects where developers and regulators demand better fire performance than basic PVC.

In Europe, where Prysmian is headquartered and where building codes such as the Construction Products Regulation and related harmonized standards shape cable choices, Afumex Green 1000 is marketed as a compliant, halogen-free option for fixed installations in buildings. Installers use it for lighting circuits, socket wiring and small power lines that run through cable trays, ducts and conduits.

Technical characteristics and use cases

Afumex Green cables typically feature cross-linked polyethylene (XLPE) or similar thermoset insulation engineered to be halogen-free and low-smoke, paired with non-halogenated outer sheaths in compatible formulations. Conductors are usually copper, with cross sections sized for common building circuits from lighting feeds to heavier loads such as small HVAC equipment.

The Green 1000 variant aligns with supply voltages used in building systems, and is designed for fixed wiring rather than flexible cord applications. Contractors pull it through plastic conduits embedded in walls, lay it in ceiling trays or run it under raised floors in commercial buildings where fire performance and cable identification matter during maintenance.

On site, installers report that low-smoke, halogen-free cables like Afumex Green feel slightly different compared with traditional PVC: the jacket surface often has a more rubbery texture, and the cable can be marginally stiffer at lower temperatures. That can influence how crews plan bends and tray layouts, especially in tight ceiling voids.

Prysmian’s marketing materials emphasize that Afumex cables are designed to minimize visibility loss in a fire and reduce the risk of corrosive gas damage to equipment and metal structures, which can matter in data centers, hospitals and transport hubs. Those environments contain critical electronics and dense human traffic, so cable fire performance plays into risk assessments for designers and insurers.

Standards, regulation and safety language

Fire performance for building cables is defined through multiple standards and regional test methods, including metrics for flame spread, smoke density and halogen acid gas content. In the European Union, these feed into the Construction Products Regulation and the associated CE marking system, which classify cables based on energy contribution and fire behavior.

Prysmian positions Afumex Green 1000 to meet relevant classifications in these frameworks, though detailed labeling and performance classes depend on specific product codes and national implementation. Engineers selecting the cable typically cross-reference local standards and building regulations to ensure alignment with required fire classes for corridors, escape routes and occupied rooms.

All of this makes the product attractive for developers who need to balance cost against safety obligations. While the cable usually carries a premium over basic PVC wiring options, designers may treat that as a modest insurance cost, trading slightly higher material bills for lower potential liability and better resilience in case of an incident.

Global projects and US relevance

Afumex Green 1000 is primarily framed as a European and international building cable, with Prysmian highlighting its use in large infrastructure and commercial projects across multiple regions. Many US-based engineering and construction firms work on cross-border projects where European or Middle Eastern codes apply, and low-smoke, halogen-free cables often feature in their specifications.

For US investors, Afumex Green 1000 matters less as a standalone product and more as part of Prysmian’s broader low-voltage building and infrastructure portfolio, which supports revenue streams in construction, utilities and real estate developments globally. As safety regulations tighten and urban building density increases, demand for fire-conscious wiring solutions tends to expand.

If a US hospital or data center is built under European code frameworks or by global consortia, cables similar to Afumex Green 1000 may be used for core circuits, reflecting trans-Atlantic safety trends. The product also illustrates how Prysmian integrates materials science and regulatory compliance in its catalog rather than pushing only the cheapest, most basic wires.

Prysmian and its stock context

Prysmian, based in Italy, is one of the world’s largest manufacturers of energy and telecom cables, supplying everything from submarine power lines to household wiring. Afumex Green 1000 slots into its long-running building cable portfolio, which complements higher-profile products like high-voltage transmission lines and fiber-optic networks.

Prysmian stock trades on Borsa Italiana (BIT: PRY) in euros and has no US listing, though American investors can access the company via certain international brokerage platforms. Afumex and related building cables form part of the company’s recurring business with infrastructure and construction clients, contributing to steady revenue in its Energy segment.
